Two models of recently reported high workload associated with vigilance tasks are the direct-
cost and indirect-cost views. The former attributes high workload to the need for continuous …

Vigilance or sustained attention/vigilant attention refers to the ability of observers to maintain
their focus of attention and remain alert to stimuli over prolonged periods. A variety of …

Decrements over time in sustained attention (vigilance decrement) have been attributed to
filtering, reduced tonic arousal, neural habituation, and related factors. A recent taxonomic …

Recent evidence mandates a revision of the traditional view that vigilance tasks place a
minimal information processing load upon observers (cf. Dember and Warm, 1979). Much of …

Vigilance or sustained attention refers to the ability of observers to maintain their focus of
attention and remain alert to stimuli over prolonged periods of time (Warm, 1977, 1984 …

Robertson, Manly, Andrade, Baddeley, and Yiend (1997) proposed that the decline in
performance efficiency over time in vigilance tasks (the vigilance decrement) is …

Objective: We describe major discoveries and developments in vigilance research.
Background: Vigilance tasks have typically been viewed as undemanding assignments …

The resource view on vigilance performance was tested. First, a low demanding task was
compared with a similar low demanding task in which stimulus presentation was less …

The vigilance decrement has been described as a slowing in reaction times or an increase
in error rates as an effect of time-on-task during tedious monitoring tasks. This decrement …

Vigilance, or the ability to sustain attention for extended periods of time, has been of interest
to the human factors and ergonomics community for 70 years. During this time, several …
